getAttribute()

[VENKATESH NADAGOUDA]

can we use getAttribute() to read the contents of querystring.If not why

[Mike Curwen]

Yes, that's the exact right method to use.

If you are trying and having trouble, post some of your code.

My first question would be: do you have a file upload form element in the form? If so, this will not play nicely with getAttribute()

[Dominic Paquette]

Hi,
Did you try HttpServletResponse.getQueryString() ?

[Bosun Bello]

getQueryString() is actually a method of HttpServletRequest.

Dear All
Firstly thank u,
now which is more advantageous getAttribute() or getParameter()

[Mike Curwen]

You know what? I'm totally out to lunch. I must have had a brain freeze.

If you are submitting a form, or click on a link that contains name/value pairs, then the way to get these items is with getParameter()

So if the URL to the servlet looks like:

http://www.localhost:8080/app/servlet1?name=foo&name2=bar

then here is how you access the name and name2 parameters...

String name = request.getParameter("name");
String name2 = request.getParameter("name2");
String qString = request.getQueryString();
/* * qString would contain "name=foo&name2=bar" **/

When you programatically *add* things to a request or a session, the way to get these 'extra' things is within the attribute space. setAttribute() and getAttribute() are used for this purpose. Only those things that you "set" with setAttribute can be "gotten" with getAttribute.

Sorry for that confusion!
